  1. 1. Control and Analysis of Pulse-Modulated Systems

    University dissertation from Stockholm : KTH

    Author : Stefan Almér; KTH.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pulse-width modulation; Periodic systems; Stability analysis; Harmonic analysis; Lyapunov methods; Dynamic phasors; Harmonic transfer function; Switched mode power converters; Sampled data modeling; H-infinity synthesis; MATHEMATICS Applied mathematics Optimization; systems theory; MATEMATIK Tillämpad matematik Optimeringslära; systemteori;

    Abstract : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. READ MORE

  2. 2. Design of High-Speed Analog-to-Digital Converters using Low-Accuracy Components

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Timmy Sundström; Linköpings universitet.; Linköpings universitet.; [2011]

    Abstract : The scaling of CMOS technologies has increased the performance of general purpose processors and DSPs. However, analog circuits designed in the same process have not been able to utilize the scaling to the same extent, suffering from reduced voltage headroom and reduced analog gain. READ MORE

  3. 3. Electrical Characterisations of Bearings

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Abhishek Joshi; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ball bearing; Equivalent circuit model; Lubricants; Bearing Capacitance; Spherical bearing; Mechanical bearing; Bearing currents; Electrical conduction; Electrical characterisation;

    Abstract : Mechanical bearings are an integral part of industry, and are used in various places in order to reduce friction between two interacting surfaces and are used to transmit power and loads. Mechanical bearings are one of the most extensively used components within the wind industry, but on the other hand they are also one of the most dominantly failing failed components. READ MORE
